Abstract (en)
[origin: EP0578428A1] A process for making a tip microstructure (22) in amorphous silicon or polysilicon (12). A layer of nitride is first deposited on the amorphous silicon or polysilicon (12). Then the amorphous silicon or polysilicon (12) is roughly patterned to form the base (24) of the tip structure (22). The tip is carved out of the amorphous silicon or polysilicon (12) by using an oxide growth process that is controlled by the amount of dopant in the amorphous silicon or polysilicon (12). After the tip is carved, the oxide is stripped away exposing the tip (26). <IMAGE>
